## Long description

The Helukabel M40 polyamide lock nut is a professional-grade fastening component designed to provide secure and reliable installation for cable glands. Manufactured from high-quality, durable polyamide, this grey lock nut ensures long-lasting performance in various industrial and electrical environments. The design features a collar that offers a larger sealing area, which simplifies the process when using an additional O-ring for enhanced environmental protection.
Advantages
This lock nut is engineered for robustness and ease of use in demanding wiring projects. The polyamide material provides excellent resistance to mechanical stress and environmental factors, ensuring that cable glands remain firmly in place. The inclusion of a collar design significantly improves the sealing interface, allowing for a more secure connection that prevents moisture and dust ingress when paired with appropriate sealing accessories.
Suitable for
Securing cable glands in industrial control panels
Electrical installations requiring strain relief
Projects involving junction boxes and enclosures
Applications where a reliable, vibration-resistant fastening is necessary
When it may not be suitable

It is intended for use with standard polyamide cable glands and may not be compatible with specialized metallic or heavy-duty industrial glands that require specific torque or material properties.
Key specifications
Thread size: M40
Material: Polyamide
Colour: Grey
Quantity per pack: 50 pieces
Design: Counternut with collar
How to use
To install the lock nut, thread it onto the cable gland from the inside of the enclosure or panel. Ensure the collar side is facing the surface to maximize the sealing area. Tighten the nut firmly by hand or using an appropriate tool to secure the gland against the housing wall. If an O-ring is being utilized, ensure it is properly seated against the collar before final tightening to achieve the desired level of environmental protection.
What to consider before purchase
Verify that your cable gland thread size is M40
Ensure the material compatibility matches your specific enclosure type
Confirm the quantity required for your project scale
Usage recommendations
For optimal performance and environmental sealing, ensure the surface around the entry point is clean and flat. When using an additional O-ring, verify that it is correctly positioned against the collar of the lock nut to maintain the integrity of the seal.
